The following formulas and equations can be used to calculate the capacitance and related quantities of different shapes of capacitors as follow. The capacitance is the amount of charge stored in a capacitor per volt of potential between its plates. Capacitance can be calculated when charge Q & voltage V of the capacitor are known: C = Q/V
The energy of a capacitor is calculated using the equation W = Q · V, where W is the work, Q is the charge, and V is the voltage. However, in a capacitor, we must consider the nonideality of the charging process. The charge accumulated in the capacitor starts at 0 and ends at Q after a certain time.
C = Q/V If capacitance C and voltage V is known then the charge Q can be calculated by: Q = C V And you can calculate the voltage of the capacitor if the other two quantities (Q & C) are known: V = Q/C Where Reactance is the opposition of capacitor to Alternating current AC which depends on its frequency and is measured in Ohm like resistance.
These calculations are included in the free Espresso Engineering Workbook. Total capacitance of series-connected capacitors is equal to the reciprocal of the sum of the reciprocals of the individual capacitances. Keep units constant.
Q = C V And you can calculate the voltage of the capacitor if the other two quantities (Q & C) are known: V = Q/C Where Reactance is the opposition of capacitor to Alternating current AC which depends on its frequency and is measured in Ohm like resistance. Capacitive reactance is calculated using: Where
The Average power of the capacitor is given by: Pav = CV2 / 2t where t is the time in seconds. When a capacitor is being charged through a resistor R, it takes upto 5 time constant or 5T to reach upto its full charge. The voltage at any specific time can by found using these charging and discharging formulas below:
